statically typed vs dynamically typed language

Statically typed languages 'type check' at compile time and the type can NOT change. (Don't get cute with type-casting comments, a new variable/reference is created).

Dynamically typed languages type-check at run-time and the type of a variable CAN be changed at run-time.

Python, bash - dynamically typed language

                      - interpretable

c, c++,go  - statically  typed language

                  - compilable
